A crime fighting canister created to look like a fire extinguisher is now being used in the classroom to keep students and teachers safe.

"We know that we need to be prepared to address any kind of shooting or any threat that takes place," said Troy McIntosh, Head of School with Worthington Christian Schools.

The campus recently installed nearly two dozen "Threat Extinguishers" inside its schools and administrative offices. Each Threat Extinguisher system is designed to also sound an alarm the second it is removed from its base.

"An alarm notification is sent to local first responders," said McIntosh, "faculty and staff can receive text messages letting them know there is a threat in the location."

Up to 1,000 people can receive the text within seconds.

ABC 6/Fox 28 first reported on the Threat Extinguisher last year, the brain child of Westerville general home contractor Sam Fasone, who came up with the idea a few years ago following a deadly Planned Parenthood shooting in Colorado.

Fasone says he has placed the Threat Extinguisher in at least two other school districts in Ohio and is working to put it in a Central Ohio church.

Worthington Christian students and staff have been trained how to use the extinguishers which have been placed in selected classrooms, hallways, and offices.

Expenses include a one-time installation cost and a monthly fee.

An investment McIntosh prays will never be put to use.

"It certainly gives us peace of mind," he said, "if we have it on campus, we have a way to deal with it."
